Interactive Guided Ultrasound Examinations Done by Non-experts of Ultrasound Imaging

The primary objective of this study is to assess the feasibility for non-expert users (medical professionals but non-certified sonographers) to acquire parasternal, apical and subcostal views of suitable quality by using an existing ultrasound device (CE-marked, available in the market) and an additional guidance system (software prototype + probe motion tracking device). Such a system will help the user to place the probe on the patient and provide guidance for optimal acquisition of parasternal, apical and subcostal views.

The secondary objective of this study is to assess the feasibility for non-expert users to reproduce a simple clinical protocol by using an existing ultrasound device and the same additional guidance system.
